The teacher developed a series of four quarterly take-home exams for their Math 4R Pre-Calculus students over the course of the year through discussions with their peer coach. The exams are done in groups and aim to challenge students to think critically and solve problems requiring more than one class period. Students learn best by explaining topics to peers, and the exams have helped students become more proficient in independently learning new material and taking ownership over topics. As a result, students are now more organized, focused, and able to make coherent mathematical statements and arguments in class.
